thanks. Actually i got some cable from radio shack for the rear (rb3) - it wasnt radio shack though it was monster xp hd i got a good deal and it actually sounded a lot better than the cheaper stuff i had before - acoustic research. my ears could tell the difference right away, and it wasn't psycho because i did not really expect to hear any improvement. perhaps something else could explain it but i wouldnt know. I decided to try it on the front where i have monster original and i felt that there was some things that were better but since it was a skinnier, 20 foot lenght i kept it on the rear as it wasnt well suited for the front. After that I decided to order some z2 from wild west but soon received a 50 or 100 ft s video cable %*& which i returned (i dont know if theyre going to refund me yet or not, im still waiting)!
